We really enjoyed our three weeks at this here. There were a couple of minor issues on the first day but the host Kay was very responsive and took care of everything for us. Kay went over and above to help us out for the duration of our stay and we were lucky enough to meet her in person.
The apartment itself had more storage than you can see in the pictures and there is also a second air conditioning unit in the bedroom which you cannot see from the pics, both were a pleasant surprise. Mattress was firm but super comfy and the couch is a good as it looks. Wi-Fi was from a router using a mobile sim card, not super fast but was fine for streaming content to the TV without buffering as we both had local sim cards for our phones.
The location is what sets this place apart. Close to a major road and both a BTS and MRT station, but just set far enough back to be a nice and quiet. You can walk out the front through the Lotus shopping centre to the Ha Yaek Lat Phrao BTS station, which also gives covered walkway access to the Central Lat Phrao Shopping Centre, Union Mall and the MRT underground station.
Very vibrant nightlife in the area with restraints, street food an a surprising number of bars with live music. To get to the more touristy parts of Bangkok is just 20 minutes away on the airconditioned Skytrain, if that is what you are into.
I will be looking for this place again next time we are in Bangkok.
